There is always great anticipation with the release of our Rivals100 and Rivals250, and with our first re-ranking since February, this week's release is already creating quite a bit of buzz.

So as a Memorial Day teaser, Rivals.com national analyst Mike Farrell gives you a sneak peek of some of the prospects rising and falling this week, led by Alpharetta (Ga.) Milton defensive end Carl Lawson.

So here is just a small sample of a few notable risers and fallers, listed alphabetically, that will be revealed this week by Rivals.com.

RISING

LB Alex Anzalone, Wyomissing (Pa.) Wyomissing Area - We knew Anzalone was good as evidenced by his four-star ranking. Additional film review, a glimpse of how good he is in coverage in person and his added size showed he needed to be much higher.

LB Deoundrei Davis, Cypress (Texas) Cypress Woods - We only got a small glimpse of Davis before we did our first release and now after further review, this kid is special.

DB Tahaan Goodman, Rancho Cucamonga, Cali. - Goodman not only impresses on the camp circuit with his coverage ability, but more film work shows even more just how physical he is.

RB Derrick Green, Richmond (Va.) Hermitage - No one in the country looks better on the hoof at running back than Green and he showed he has improved his ability to be an every down back in college.

DE Carl Lawson, Alpharetta (Ga.) Milton - Lawson dominated every camp he attended, additional game film has emerged and the biggest question remains - will he be a five-star?

LB Mike Mitchell, Plano (Texas) Prestonwood Christian Academy - A huge linebacker who can play outside or inside, moves well laterally and is excellent in coverage? That's a rare talent and it's what we've seen from Mitchell since our first ranking.

RB Taquan Mizzell, Virginia Beach (Va.) Bayside - What happens when you attend every camp possible, win positional MVP at nearly all of them and show some of the best feet in the class of 2013? You move up, that's what happens.

OL John Montelus, Everett, Mass. - Montelus didn't camp anywhere this spring, but film showed his ability to play both tackle and guard - and be a downfield menace.

DE Torrodney Prevot, Houston (Texas) Alief Taylor - Prevot was a three-star in our first ranking because we had just a little bit to go on. Since then we have reviewed much more film and seen him in person, and his quickness and athleticism are high end.

DE Tim Williams, Baton Rouge (La.) University Lab - Williams emerged late in our first ranking and after much more research and film work, he was clearly undervalued in February.

FALLING

WR Marcell Ateman, Wylie (Texas) East - Ateman is a guy who was simply passed by many other wide receivers after in-person evaluation and wasn't quite as good as we originally thought.

QB Tra'von Chapman, Kent (Ohio) Theodore Kent Roosevelt - After seeing how Chapman stacks up against some of the top quarterbacks not only from his region but from around the country, he needed to drop a bit as he is talented but raw.

OL Steve Elmer, Midland, Mich. - Elmer struggled against some of the more elite linemen we saw and his technique could use a lot of work. Just too raw for such an original lofty ranking.

OL Austin Golson, Prattville, Ala. - Are we punishing Golson for being dominated by Dee Liner at the Rivals.com/VTO Sports Alabama Elite 100? Not completely, but his athleticism and speed come into question as he'll be facing that kind of talent in college.

DB Dashon Hunt, Westlake Village (Cali.) Westlake - After seeing most of the elite cornerbacks on the West Coast and across the country, it became clear that Hunt was just too high in comparison. Still a very good player, but not as elite as we originally thought.

DB Will Likely, Belle Glade (Fla.) Glades Central - Sometimes you can be a very good prospect and be very athletic but size can hold you back from a lofty ranking. With so many big receivers out there these days, this came down to being 5-foot-8, tops.
